IMPROVEMENT IN APPARATUS FOR MANUFACTURING WIRE.

Specification forming part of Letters Patent No. 211,458, dated January21', 1879; application filed September 30, 1878.

i To all whom it may concern:

Be it known that I, HENRY GHIsnoLM, of Cleveland, in the county ofOuyahoga and State of Ohio, have invented a certain new and ImprovedApparatus for Manufacturing Wire by Hot-Rolling; and I do hereby declarethat the following is a full; clear, and complete description thereof.

The nature of this invention relates to the art of manufacturing wire byhot-rolling, instead of by the expensive and laborious method ofannealing and drawing hitherto practiced, which will be more fullydescribed hereinafter, and set forth in the claims.

. For a full and complete description of said nvention, reference willbe had to the follow- 1ng specification, and to the accompanyingdrawings, making apart of the same, in which- Figure 1 is a plan view ofthe furnaces, reel, and rolls. Figs. 2, 3, and 4 are side elevations.

Like letters of reference refer to like. parts in the several views.

A represents the primary furnace, which may be of any suitable size, asthe work may require. B is the fire-place; B, the ash-pit, and C, Fig.3, the bridge-wall. A portion of the outer wall and top of the furnace Ais shown as broken away in Figs. 1 and 3, that the inside may be seen.

D is a horizontal projection of the bridgewall, extending partially overthe chamber E .of the furnace, which serves the purpose of reverberating the heat, and of which chamber F is the bottom or floor. Near thefront end 9f the said floor are apertures a, Fig. 1, openin g into theflue Gr, Fig. 3, underneath.

Theauxiliary heating-chamber is in open relation with the primaryfurnace through the intervention of the auxiliary furnace H and the flueI, said flue I being a continuation of the flue G. The auxiliary furnaceopens into the auxiliary heating-chamber through the.

aperture 1), and of which chamber K is the floor, Fig. 2. At theopposite end of the aux- Extending forward in front of the door of i theprimary furnace are a pair of ways or guides, Q, Figs. 1 and 2, betweenwhich is fitted, so as to slide freely, a block, It, in which is mounteda spool or drum, A, free-to rotate in the block, and provided with thespindle indicated by the dotted lines 6.

G are a pair of rollers journaled in suitable housings arranged directlyin front of the end of the auxiliary heating-chamber, and in suchrelation to the door thereof as to be in line with the same, as shown inthe drawings. The practical operation of the abovedescribed severaldevices is substantially as follows: A coil or coils of wire or rods, asthey come from the mill, are placed in the chamber of the primaryfurnace, as indicated at n, wherein they are heated to a proper workingdegree, from which a heated coil is then taken and placed upon the drumA, which, for that purpose, is pushed along to the door of the furnace,and then brought back to the position shown in Fig. 1.. The end of thecoil is taken and passed through the auxiliary chamber and extended tothe rolls, as indicated by the dotted line at m.

To facilitate the introduction of the end of the coil into and throughthe chamber, a narrow horizontal slash or opening, 1;, Fig. 2, is madein the side of the chamber, through which the wire is quickly passedinto said chamber. The slash or opening is then closed by an apron ordoor, which may be of any suitable material, and attached to the wall ofthe chamber by any appropriate means. The gripe of the rolls upon thewire as it is being reduced by them draws upon it and uncoils it fromthe drum, and draws it through the chamber, wherein the proper heat ofthe Wire for rolling is obtained, so that the wire passes to the rollsin a sufficiently-heated state to be easily worked by them.

The wire may be introduced into and passed through the chamber J bypassing it directly through the doors P, in which case the slash oropeningi is closed up. It is, however, preferred to use the opening asherein described, and which may be in the top of the chamber instead ofin the side. In the event the waste heat from the primary furnace is notsufficient to heat the auxiliary heating-chamber to the desired degree,the auxiliary furnace H is then used for that purpose, and if furtherheat is necessary the auxiliary furnace L can be used in connectiontherewith.

The rods from which wire is to be rolled can be conducted at once intothe primary furnace from the rolls while they are yet hot, and therebysave the time and expense of reheating them in the furnace.

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination of the primary furnace, A, constructed as described,drum A, Ways Q Q, heating-chamber provided with the slot 41, throughwhich the end of the coil is inserted, as described, and reducing-rollsO.

2. The furnace A, having the fire-wall D, extending partially over thefurnace-chamber as a hood, and the drop-fines a a, in combination withflues G and I, furnace H, and reheating-chamber J, substantially as andfor the purpose described.

3. The combination of the primary furnace,

'A, constructed as described, drum A, ways Q Q, heating-chamber providedwith the slot i, auxiliary furnaces H and L, and reducing rolls 0, allsubstantially as and for the purpose described.
